ObjectLongTreeMap

public ObjectLongTreeMap()

Method Detail

put

public void put(Object key,
                long value)

Associates the specified value with the specified key in this map. If the map previously contained a mapping for this key, the old value is replaced.

Parameters:

key - key with which the specified value is to be associated.

value - value to be associated with the specified key.

inc

public void inc(Object key,
                long quantity)

Incremente the value associated with the specified key. If this key did not exist, it is created and the value is set to '1'.

Parameters:

key - key for which the specified value must be incremented.

quantity - the quantity to increment

inc

public void inc(Object key)

Incremente the value associated with the specified key. If this key did not exist, it is created and the value is set to '1'.

Parameters:

key - key for which the specified value must be incremented.

getLong

public long getLong(Object key,
                    long defaultValue)

Returns the value to which this map maps the specified key. Returns defaultValue if the map contains no mapping for this key.

Parameters:

key - key whose associated value is to be returned.

defaultValue - value to return if the map contains no mapping for this key.

Returns:

the value to which this map maps the specified key, or defaultValue if the map contains no mapping for this key.

getSum

public long getSum()

Returns the sum of the values of the map

Returns:

the sum of the values of the map

jcms-7.0.0

getSortedMapEntrySet

public static SortedSet getSortedMapEntrySet(Map map,
                                             Comparator comparator)

This method return a Sorted Set of Map.Entry

Parameters:

map - a TreeMap that is an ObjectLongTreeMap or composed by ObjectLongTreeMap.

comparator - the comparator to sort objects.

Returns:

SortedSet of Map.Entry

Since:

jcms-7.0.0

getGreaterComparator

public static Comparator getGreaterComparator()

Sort ObjectLongTreeMap from larger to smaller

getLowerComparator

public static Comparator getLowerComparator()

Sort ObjectLongTreeMap from smaller to larger

getSortedKeyComparator

public static Comparator getSortedKeyComparator(List sort)

Sort ObjectLongTreeMap ordered by a predifined List

getSortedKeyComparator

public static Comparator getSortedKeyComparator(String[] sort)

Sort ObjectLongTreeMap ordered by a predifined List
